Do you do solar installation?

PotatoSalad:

173ah 48v
200ah 48v
That's if you are running a 48v system

Good day and thanks for your previous response
Please what if I'm using a 24V inverter system, what is the rating of the batteries I'll need?

I believe he has the same in 24v system too.
I bought my 173ah 48v from him last November. Grade A lithium cells.

Hello everyone,

Please, I want to get a solar inverter system that can power a 200+ liters freezer.

I would appreciate any advice on how to get it done and how much it will cost.

Thank you.

Hello my people

I need help. Months back, I had a 6 units of battery, 10kva 48volts inverter and 14 panels installed for me. Though, only 4 batteries are running at the moment and the other two are just connected to charge.

Recently, I noticed a drop. The backup doesn’t last at all. This system usually takes me 24 hours and repeat if there’s no light. But now, once the sun goes down, it doesn’t serve past 6 hours sef that’s even if I’m running just a rechargeable fan and a light bulb. Then, this system would take me till dawn even with my fridge on and I won’t use past 40% of the total charge overnight.

Initially, I thought it was the charge controller so I had one of my boss swap his charge controller with mine, but no changes. Then I realized that when I charge with NEPA, it works very fine. But when I charge with solar, it doesn’t last at all. Meanwhile… I have 14 whole panels.

One of my boss said that dusts has covered the panels due to the harmattan that we need to clean the panels panels which we did.

In summary, system lasts and works very fine when charged with NEPA, but doesn’t last at all when I charge with solar panel.

What could be the issue? I’ve been substituting with fuel because our light is not always constant.

Please, help a brother.

First you need a good audit of your system which you can do yourself..... recently solar generation has reduced due to the season we are in. What are the specs of your panels and batteries.

3.5kva is okay with 4 flooded batteries and 12 320watt panel

How much is the cost of this setup please.

Good day everyone
I need a two to three bedroom in oworo,iyanaoworo,ifako,sawmill or gbagada axis

I have 3.5 kva inverter running on 2 dry cell batteries, tho no panel. I run my Samsung inverter fridge without stress. Bought fireman AC inverter to use on it but I fireman AC was a scam.

Tips to use inverter especially if you don't have solar panels. Avoid ceiling fans, industrial standing fans, high Watts bulbs. Use low consumption appliances. If you must use ceiling fan, buy inverter ceiling fan.

Nice

How much was the cost of your installation back then

Solar Panels with original capacity available

What is available now and today prices

Original capacity tokunbo panels
250w poly...56k
200w mono...56k
310w mono... 85k
460w mono....130k

Not Jinko panels but half cut modules:
550w mono (new without carton)...145k
550w Bi-facial (new without carton)... 150k

babkazy:
you are right , but lithium battery is very expensive and can explode easily

Explode ke

Dont mind jumia.

As I was about to checked out the amount 22,000 turn to 27,000

It's now 40k. Which way Nigeria?

Very dangerous, but with care you will be safe even normal wet cell battery do explode

Normally charging via Nepal light and solar is equal, both are good but Nepal is better as the rate of discharge with Nepal is low

Okay. Never knew they explode. Thanks.

Please help! I have a De-bull 2500VA-24V-50A inverter with 2 x 200Ah tubular battery connected to it using a 100AH breaker, every time I switch on the breaker, it trips and comes with error message.

What can I do to rectify, please


I just realised that what should be the AC mains cable was swapped with the (inverter) Output!


Manufacturer error!

Hello man, Have you gotten a solution for it?

Good day to everyone here, please I need help on my diy , I need help on my solar set up, I have a panel with the following data sheet.
Rated max power 190w
Current at pmax 5.18A
Voltage at pmax 36.7v
Short circuit current 5.6A
Open circuit voltage 44.8v

Cell type ; mono
Maximum system voltage 1000v

and a mpw charge controller with the following data sheet;
Rated voltage: 12/24
Rated current: 30A
Maximum PV voltage: 50V

I have 12/ 75ah battery connected to the charge controller with hope of using the panel to charge, what I observed was that when the sun is at peak the battery indicator on the controller shows full bar and voltage increases up to 17v on the controller. recently I forgot to manually disengage the charging after about 7hr and when I remembered I discovered the battery has swollen, though still working.
please is there anything wrong with my connection? how do I prevent the charge controller from overcharging the battery without me disengaging it manually? did I need to make any adjustment, kindly help pls.

The cc is not regulating properly, because I see no reason why a 30A PWM can't control and monitor the charging

How SRVGrid Is Providing Affordable Renewable Energy Solutions For Nigerians

Adequate access to electricity supply is a significant concern that has lingered for many years in Nigeria. As of 2021, over 85 million Nigerians lacked access to electricity, which is due to the insufficiency of the national grid to serve the teeming population. This has led to a great demand for petrol and diesel-run (fossil fuel) generator sets as a popular alternative to power supply. While they are not only expensive to buy, generator sets produce greenhouse gases like carbon monoxide and nitrogen oxides, which pollute the environment and deplete the ozone layer.

However, renewable energy’s environmental sustainability and economic effectiveness have diverted keen attention to solar power generation - a move towards a green environment. Today, solar energy is the latest innovation in producing electricity in Nigeria, and it is more efficient than petrol- and diesel-run generator sets. This is why you can see solar installations at homes, offices, shopping complexes, hospitals, schools, rural areas, government institutions, etc., to have a round-the-clock uninterrupted power supply.

Meanwhile, it is a common belief by an average Nigerian that access to solar energy is exclusively for high-income Nigerians – tagging it a luxury commodity. This is untrue, as everyone can use this renewable energy at home and other places, which is the sigh of relief SRV Grid is bringing to all Nigerians.

Good morning, I want to get batteries for a 2.5kva or 1.5kva hybrid inverter. I just noticed that two 220ah batteries give a total of 440ah at 594k while four 150ah batteries gives a total of 600ah at 580k. By my local man logic, the 150ah option seems better to me cus I get about 160ah more battery capacity. Pls, those who are experts, is this my logic correct and can I go for this 150ah option?
